Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed November 5, 1913. Serial No. 799,291.

To all whom it may concern:

Be it known that I, DEUNBORD BEAUDRY, residing at the city of Montreal,in the Province of Quebec, in the Dominion of Canada, have inventedcertain new and useful Improvements in Circular-Saw Attachments; and Ido hereby declare that the following is a full, clear, and exactdescription of the same.

The invention relates to improvements in circular saw attachments asdescribed in the present specification and illustrated intheaccompanying drawings that form part of the same.

The invention consists in a disk wheel adapted behind the circular sawto prevent the wood, especially the thinner wood, from jumping over thesaw as often happens. The disk enters the split and helps the saw individing the wood, especially if the wood is green. This disk isadjustable and held in place by a sliding plate, sliding in a rack, thesaid rack being supported by an extensible arm which is adapted to astand socurely bolted to the saw table at any. suitable part thereof. Tothe sliding plate is pivotally secured a protector for the saw toprevent accidents which so frequently happen.

In the drawings, Figure 1 is a perspective view of a portion of acircular saw table showing the attachment adapted thereon. Fig. 2 is anenlarged perspective view of the adjusting mechanism. Fig. 3 is anenlarged cross section on the line A--B through the rack.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the circular saw table having fittedthereon the usual circular saw 2 and guide 3.

41 is a stand, preferably of cast material secured to the table 1 bymeans of the bolts 5, said stand extending upwardly and outwardly inright angular shape at 6, the said end 6 having therein the' bolt hole 7shown in dotted lines.

8 is a disk plate beveled at its edge, and secured to the lower end of aplate 10 sliding in the way 11. The said disk plate 8 is so arranged asto enter the slit made by the saw and so free the latter.

12 is a protector plate for the saw, pivotally connected at 13, to thelower end of the plate 10 one end of the said protector plate resting onthe wood to be sawed and completely covers the exposed edge of the saw.

14 is a lug at the upper end of the plate 10 and projecting outwardlythrough the slide way 15 from the said plate 10 and having the threadedhole 16.

The way 11 has the head 17 through which is a hole 18 horizontally boredand immediately below said head 17, projects the lug 19 having the hole20 adapted to receive a threaded rod 21 which is threaded in the hole 16of the lug 14:.

22 are collars rigidly secured to the rod 21, and 23 is a crank. If thecrank 23 is turned in one direction the threaded rod 21 passing throughthe hole 16 will raise the disk 8 and thus take the same out ofengagement with the slit in the wood, or adjust it to any heightrequired.

24 is a tube having the longitudinal slot 25 and the flange 26 at oneend and having an outwardly extending end 27 of smaller diameterextending from said flange. The said tube engages the projecting rod orarm 6 and slides thereon, thus enabling the operator to extend orshorten the device according to the width of the table, 28 is a boltpassing through the bolt hole 7 and the slot 25, and 29 is a nut forsecuring same rigidly in any required position.

30 is a lug extending upwardly from the head 17 and having the hole 31therein.

32 is a pin held to the lug 30 in the hole 31 by means of the small coilsprings 38, the said pin engaging one of the holes 34 in the flange 26.By this means any inclination may be given to the plate 10.

This invention is very cheap to manufacture and a great improvement onthe present circular saw attachments in not only protecting theoperator, but in preserving and helping the saw.

What I claim is In a circular saw attachment, the combination with thetable and saw of a stand rigidly secured to said table and having an extension parallel to the axis of the saw, a tube telescoping on saidextension and a bolt for locking same in an adjusted position on saidextension, said tube having a collar on its outer end with a series ofholes therearound,

a right angular member Whose one end pivlower end of said plate andadapted to turn otally engages the end of said tube beyond in the slitmade by the saw in the ood. 10 the collar, said member having a pinpass- Signed at Montreal, Quebec, Canada, this ing through a lug forengagement With said 25th day of August, 191 3 '7 V N U holes, a plateslidably engaging the other DEUNBORD BEAUDRY.
